Is there any other water-cooled wall anti-wear technology for circulating fluidized bed boilers other than metal spraying?

　　For enterprises using circulating fluidized bed water-cooled wall wear has been a headache for everyone, the water-cooled wall once the wear and tear leak burst pipe problems, the adverse effects are still very large. As long as the water-cooled wall is worn and burst, we should know how difficult it is to overhaul the work, not to mention the huge economic losses caused.

　　In order to solve the problem of circulating fluidized bed boiler wear, many companies have adopted metal spraying technology. Metal spraying has been applied in many industries, and metal spraying technology has been applied to the water cooling wall in the early days to solve the problem of water cooling wall wear. The advantage of metal spraying is that the construction is simple and the initial anti-wear effect is good. But metal spraying anti-wear is also flawed, metal spraying on circulating fluidized bed boiler wear problems can only cure the symptoms not Zhang, anti-wear form more passive, the water-cooled wall of the burst tube cycle of less than 1 year, a long time will need to be sprayed again, which also invariably increases the cost of anti-wear enterprises.

　　Grille anti-wear installation real picture

　　In order to solve the problem of water-cooled wall wear that is difficult to completely cure, grille anti-wear technology was introduced. The grid anti-wear technology is currently only applied to circulating fluidized bed boiler water-cooled wall wear problem, which can completely solve the circulating fluidized bed boiler water-cooled wall wear problem. He is different from metal spray anti-wear because the technology is not passively thickening the water-cooled wall, but more actively anti-wear treatment for the water-cooled wall.

　　According to the analysis, the main reason for water-cooled wall wear in circulating fluidized bed boilers is the cutting and scouring of the water-cooled wall by the material particles moving at high speed in the furnace chamber. Once the water-cooled wall is equipped with grating anti-wear plate, several initiatives to avoid the high-speed movement of material particles on the water-cooled wall damage, and finally completely solve the problem of water-cooled wall wear.

　　The emergence of grating anti-wear technology has made a huge change in the form of water-cooled wall anti-wear, and it is not a dream to completely solve the problem of water-cooled wall wear.
